To all whom it may concern:

Be it known that I, JOHN WELLBY, of Frederickton, in the county of York,in tlie Prov.- inceof New Brunswick and Dominion of (Janada, haveinvented a new and useful Improvement in Railway-Dust Preventer, ofwhich the following is a specification:

Figure 1 is a perspective view'of a car to which myimprovement has beenapplied. Fig.

A represents the car-body; B, the end plat-' form; (J, the steps; D, therailings; and E, the

brake-shaft; about the construction of which parts there is nothing new.F is a frame, made with close triangular ends f, and which is designedto be securedto the lower part'of the car body A, and which shouldproject downward so as to be as close to the ground as practicable. Tothe upper parts of the ends of the frame F are pivoted the journals of aroller, G. To the roller Gis attached one edge of a canvas screen, H,the lower edge of which, when unrolled, is designed to be secured to thelower bar of the frame F, so that by detaching the lower edge of thescreen or blind H it may be rolled upon the roller G to giveconvenientaccess to the wheels when desired. The roller G may be turned to rolland unroll the blind H by means of a handle or crank, I, permanently ordetachably attached to the end of one of the journals of the said rollerG. The roller G and screen H should be detachable, so that they may bereadily attached to the frame F of any carriage. J are the end screens,which consist of a frame covered permanently with a cover of wood orthin sheetiron. The ends of the screens J are made close and triangular,and their inner edges fit closely to the inner edges of'the closetriangular ends of the frames oft-he side screens, as shown in Fig. l.The brake-shafts E pass down through holes in the end screens J, asshown in Fig. 1.

The end screens J should project so that the end screens of adjacentcars may come as near each other as practicable without danger of beingbroken.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A triangular frame, F, provided with roller to receiveflexible screen, and applied as and for the purpose described. A
